Answer: 2.1 km

Step-by-step explanation:

Given

A road map has a scale of $1:30,000$

The length of road on the map is $7\ cm$

The ratio of length on the map to the length on road is 1:30,000

Suppose x is the length of real road

$\Rightarrow \dfrac{7}{x}=\dfrac{1}{30,000}\\\Rightarrow x=30,000\times 7\ cm\approx 2.1\ km$

2x – 1+ 3x=1+ 2x - 5<br> I need the steps

Anettt [7]

Answer:

x = -5/3

Step-by-step explanation:

Combine like terms: 2x + 3x = 5x - 1 (on the left) -6 + 2x (on the right) (5x - 1 = -6 + 2x)

Get X on one side: Isolate +2x by subtracting 2x on both sides (5x - 2x = 3x) (3x - 1 = -6) Isolate -1 by subtracting 1 on both sides (3x = -5) Isolate 3x by dividing 3 on both sides.

I hope I explained it correctly

Solve this inequality: j/4 – 8 < 4. A. j < –48 B. j < 48 C. j > –12 D. j < 12

Kruka [31]

$\frac{j}{4} - 8 \ \textless \ 4 \\ \\ \frac{j}{4} \ \textless \ 4 + 8 \\ \\ \frac{j}{4} \ \textless \ 12 \\ \\ j \ \textless \ 12 \times 4 \\ \\ j \ \textless \ 48 \\ \\$

The final result is: j < 48.
